The HP/Agilent 6690A is a 6600 W system DC power supply engineered for high-power manufacturing test and burn-in applications. It delivers 0 to 15 V at 0 to 440 A with exceptional output stability, low ripple and noise, and fast programming across voltage and current ranges. Equipped with GPIB and analog interfaces, this supply supports both automated test systems and custom waveform generation while maintaining ±0.04% voltage programming accuracy and ±0.1% current programming accuracy at 25 ±5°C.
